Aurorae on Jupiter





Jupiter has aurorae. Like Earth, the magnetic field of the gas giant funnels charged particles released from the Sun onto the poles. As these particles strike the atmosphere, electrons are temporarily knocked away from existing gas molecules. Electric force attracts these electrons back. As the electrons recombine to remake neutral molecules, auroral light is emitted.

2. What does it look like when you're standing on the surface of Jupiter?

(just kidding; I know it's not a solid surface and no one could stand there even if it was)
